autoloading
[ Upstream commit 2a2565272a3628e45d61625e36ef17af7af4e3de ]
On a MSI S270 with Fedora 37 x86_64 / systemd-251.4 the module does not
properly autoload.
This is likely caused by issues with how systemd-udevd handles the single
quote char (') which is part of the sys_vendor / chassis_vendor strings
on this laptop. As a workaround remove the single quote char + everything
behind it from the sys_vendor + chassis_vendor matches. This fixes
the module not autoloading.

[ Upstream commit 83ac7a1c2ed5f17caa07cbbc84bad3c05dc3bf22 ]
Commit 2cc6c717799f ("msi-laptop: Port to new backlight interface
selection API") replaced this check:
if (!quirks->old_ec_model || acpi_video_backlight_support())
pr_info("Brightness ignored, ...");
else
do_register();
With:
if (quirks->old_ec_model ||
acpi_video_get_backlight_type() == acpi_backlight_vendor)
do_register();
But since the do_register() part was part of the else branch, the entire
condition should be inverted. So not only the 2 statements on either
side of the || should be inverted, but the || itself should be replaced
with a &&.
In practice this has likely not been an issue because the new-ec models
(old_ec_model==false) likely all support ACPI video backlight control,
making acpi_video_get_backlight_type() return acpi_backlight_video
turning the second part of the || also false when old_ec_model == false.

If chromeos_laptop_prepare_i2c_peripherals() fails after allocating memory

[ Upstream commit c3b82d26bc85f5fc2fef5ec8cce17c89633a55a8 ]
2 keymap fixes for the Acer Aspire One AOD270 and the same hardware
rebranded as Packard Bell Dot SC:
1. The F2 key is marked with a big '?' symbol on the Packard Bell Dot SC,
this sends WMID_HOTKEY_EVENTs with a scancode of 0x27 add a mapping
for this.
2. Scancode 0x61 is KEY_SWITCHVIDEOMODE. Usually this is a duplicate
input event with the "Video Bus" input device events. But on these devices
the "Video Bus" does not send events for this key. Map 0x61 to KEY_UNKNOWN
instead of using KE_IGNORE so that udev/hwdb can override it on these devs.

[ Upstream commit 40ec787e1adf302c11668d4cc69838f4d584187d ]
The call to:
size = simple_write_to_buffer(cmdbuf, sizeof(cmdbuf), ppos, buf, size);
will succeed if at least one byte is written to the "cmdbuf" buffer.
The "*ppos" value controls which byte is written. Another problem is
that this code does not check for errors so it's possible for the entire
buffer to be uninitialized.
Inintialize the struct to zero to prevent reading uninitialized stack
data.
Debugfs is normally only writable by root so the impact of this bug is
very minimal.

[ Upstream commit 0e8eb5e8acbad19ac2e1856b2fb2320184299b33 ]
Debugfs console_log uses devm memory (e.g. debug_info in
cros_ec_console_log_poll()). However, lifecycles of device and debugfs
are independent. An use-after-free issue is observed if userland
program operates the debugfs after the memory has been freed.
The call trace:
do_raw_spin_lock
_raw_spin_lock_irqsave
remove_wait_queue
ep_unregister_pollwait
ep_remove
do_epoll_ctl
A Python example to reproduce the issue:
... import select
... p = select.epoll()
... f = open('/sys/kernel/debug/cros_scp/console_log')
... p.register(f, select.POLLIN)
... p.poll(1)
[(4, 1)] # 4=fd, 1=select.POLLIN
[ shutdown cros_scp at the point ]
... p.poll(1)
[(4, 16)] # 4=fd, 16=select.POLLHUP
... p.unregister(f)
An use-after-free issue raises here. It called epoll_ctl with
EPOLL_CTL_DEL which in turn to use the workqueue in the devm (i.e.
log_wq).
Detaches log reader's workqueue from devm to make sure it is persistent
even if the device has been removed.

The call sequence suggested that misc_device /dev file can be opened
before misc device is yet to be registered, which is done only once.
Here punit_misc_dev_lock was used as common lock, to protect the
registration by multiple ISST HW drivers, one time setup, prevent
duplicate registry of misc device and prevent load/unload when device
is open.
We can split into locks:
- One which just prevent duplicate call to misc_register() and one
time setup. Also never call again if the misc_register() failed or
required one time setup is failed. This lock is not shared with
any misc device callbacks.
- The other lock protects registry, load and unload of HW drivers.
Sequence in isst_if_cdev_register()
- Register callbacks under punit_misc_dev_open_lock
- Call isst_misc_reg() which registers misc_device on the first
registry which is under punit_misc_dev_reg_lock, which is not
shared with callbacks.
Sequence in isst_if_cdev_unregister
Just opposite of isst_if_cdev_register

[ Upstream commit 39f53292181081d35174a581a98441de5da22bc9 ]
When WWAN device wake from S3 deep, under thinkpad platform,
WWAN would be disabled. This disable status could be checked
by command 'nmcli r wwan' or 'rfkill list'.
Issue analysis as below:
When host resume from S3 deep, thinkpad_acpi driver would
call hotkey_resume() function. Finnaly, it will use
wan_get_status to check the current status of WWAN device.
During this resume progress, wan_get_status would always
return off even WWAN boot up completely.
In patch V2, Hans said 'sw_state should be unchanged
after a suspend/resume. It's better to drop the
tpacpi_rfk_update_swstate call all together from the
resume path'.
And it's confimed by Lenovo that GWAN is no longer
available from WHL generation because the design does not
match with current pin control.

commit 9b024201693e397441668cca0d2df7055fe572eb upstream.
Change kstrtou32() argument 'base' to be zero instead of 'len'.
It works by chance for setting one bit value, but it is not supposed to
work in case value passed to mlxreg_io_attr_store() is greater than 1.
It works for example, for:
echo 1 > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable
But it will fail for:
echo n > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable,
where n > 1.
The flow for input buffer conversion is as below:
_kstrtoull(const char *s, unsigned int base, unsigned long long *res)
calls:
rv = _parse_integer(s, base, &_res);
For the second case, where n > 1:
- _parse_integer() converts 's' to 'val'.
For n=2, 'len' is set to 2 (string buffer is 0x32 0x0a), for n=3
'len' is set to 3 (string buffer 0x33 0x0a), etcetera.
- 'base' is equal or greater then '2' (length of input buffer).
As a result, _parse_integer() exits with result zero (rv):
rv = 0;
while (1) {
...
if (val >= base)-> (2 >= 2)
break;
...
rv++;
...
}
And _kstrtoull() in their turn will fail:
if (rv == 0)
return -EINVAL;

ACPI_PTR() is more harmful than helpful. For example, in this case
if CONFIG_ACPI=n, the ID table left unused which is not what we want.
Instead of adding ifdeffery here and there, drop ACPI_PTR()
and unused acpi.h.

commit 3abc16af57c9939724df92fcbda296b25cc95168 upstream.
Sometimes kernel is trying to probe Fingerprint MCU (FPMCU) when it
hasn't initialized SPI yet. This can happen because FPMCU is restarted
during system boot and kernel can send message in short window
eg. between sysjump to RW and SPI initialization.

gpio-lookup tables
[ Upstream commit 9d7b132e62e41b7d49bf157aeaf9147c27492e0f ]
The gpiod_lookup_table.table passed to gpiod_add_lookup_table() must
be terminated with an empty entry, add this.
Note we have likely been getting away with this not being present because
the GPIO lookup code first matches on the dev_id, causing most lookups to
skip checking the table and the lookups which do check the table will
find a matching entry before reaching the end. With that said, terminating
these tables properly still is obviously the correct thing to do.

[ Upstream commit f560cd502190a9fd0ca8db0a15c5cca7d9091d2c ]
This reverts commit 5037d4ddda31c2dbbb018109655f61054b1756dc.
Explanation why this does not work:
This change connects the simswap to the LED subsystem of the kernel.
From my point of view, it's nonsense. If we do it this way, then this
can be switched relatively easily via the LED subsystem (trigger:
none/default-on) and that is dangerous! If this is used, it would be
unfavorable, since there is also another trigger (trigger:
heartbeat/netdev).
Therefore, this simswap GPIO should remain in the GPIO
subsystem and be switched via it and not be connected to the LED
subsystem. To avoid the problems mentioned above. The LED subsystem is
not made for this and it is not a good compromise, but rather dangerous.
